Guys, water treatments and silly little bottles of "mite off" are all very good and well to temporarily relieve the snake of the annoying pests, HOWEVER mites are extremely resilient creatures who move and breed at an alarming rate. You may remove the adult mites which are on the snake at the time with the above mentioned treatments, but as soon as you put them back into their enclosure with eggs galore the whole cycle starts again.
Mites are a serious pest and MUST be eradicated in the most severe manner possible within captive collections. I cannot stress enough how much stress and grief they have caused me, and they could have possibly infected my ENTIRE collection with IBD due to how quickly they breed and spread from snake to snake. They are a vector in spreading all manners of reptile diseases and viruses... I use Front Line (flea and tick spray for cats and dogs) on the snakes and Proventamite in their cages. I soak ALL viv furnishings and plants in bleach, then spray with F10 and finally spray with proventamite. During a mite infestation I would advise you leave all hides and plants etc out of vivs. Instead opt for clean white kitchen towel layers the infested snake can bury or hide in, just long enough for the mites to die off. This makes it easy to see live and dead mites and gives the eggs little chance of survival if you are replacing the kitchen towel every day. I would also advise on washing and hovering all carpets as mites travel a long long way to find their next host. And in that time they will be breeding and laying eggs in your carpets. The next time you have a mite infestation try putting some double sided selotape on your carpets surrounding vivs and see just how many mites will be stuck on it in the morning!
